Choose the right answer to the question. Cut off is the slope of the log-magnitude curve from the following options, along with the detailed explanation.

1. At the start of the curve
2. At the end of the curve
3. Near the cut-off frequency
4. None of these

Answer: 4 The cut-off is the slope of the log-magnitude curve in Bode plots near the cut-off frequency.

## None of these statements finds correct for cut-off is the slope of the log-magnitude curve from the following options along with the detailed explanation.

Solution

The detailed solution to the question, cut off, is the slope of the log-magnitude curve

The cut-off rate is the slope of the log-magnitude curve close to the cut-off. The cut-off rate indicates the ability to discriminate between the signal and noise.

The cut-off frequency is the frequency at which the magnitude of the closed-loop frequency response is 3 dB below its zero-frequency value.

Hence, Option (C) is the correct answer.
